Self-recovery fuse is a kind of overcurrent electronic protection element, which is mainly installed in some circuits, and can prevent circuits and electrical equipment from being burnt out by overload. So what should I pay attention to when installing the self-recovery fuse?
Precautions for installing self-recovery fuse:
(1) When replacing the fuse, the power supply shall be cut off in advance, and the fuse shall not be directly pulled out for inspection when it is electrified. When replacing fuses, technicians or workers should wear insulating gloves or use other insulating articles.
(2) Choose the correct type of fuse, and generally replace the fuse with the same size and material, which cannot be thickened or reduced at will, and cannot be replaced with other wires that are not easy to fuse, so as to avoid accidents;
(3) Wipe the contact surface of the circuit so that both ends of the fuse are in good contact;
(4) Do not touch the fuse itself when installing the fuse. If you are not careful or the fuse itself is damaged, do not use it on the side, otherwise the fuse may burn out when the normal current passes, causing unnecessary power failure or other accidents;
Conclusion: Only when the self-recovery fuse is installed correctly, can the circuit be effectively protected, and if the self-recovery fuse is installed correctly, can the circuit and electrical products be effectively protected, avoid circuit failures and make the circuit safer. It is safer to use electricity.
